Application filed June 14, 1915. Serial No. 33,907.

To all whom it may concern:

Be it known that I, ALBERT F. GEORGE, a citizen of the United States, residing at Salina, in the county of Saline and State of Kansas, have invented a certain new and useful Improvement in XVindmills, of which the following is a specification.

My invention relates to improvements in windmills. I

It relates particularly to the type of windmill in which a plurality ofwind wheels are mounted on a single tower. It also relates to the type of wind mills in which the wind wheels are always held in the into-the-wind position, the blades of the wind wheels being movable by wind pressure from the into-the-wind position when the pressure becomes excessive.

One of the objects of my invention is to provide novel transmitting power connecting the wind wheel or wheels with the driven mechanism, by means of which the load may be increased under heavy wind pressure without permitting the wind wheels to race or turn too rapidly.

A further object of my invention is to provide power transmitting mechanism of novel construction which permits of a more rapid down stroke of the pump rod'than is usually obtained.

Still another novel feature of my invention resides in the gearing which lifts the pump rod by means of which an efiective pump rod lifting mechanism is obtained.

The novel features of my invention are hereinafter fully described and claimed.

In the accompanying drawings which illustrate the preferred embodiment of my invention,

Figure 1 isa rear elevation of a double wheel wind mill provided with my improve ments, some of the parts being removed and some broken away.

' Fig. 2 is a plan view of the same, someof the parts being removed and some broken away. 7

Fig. 3 is a side elevation of the same, some of the parts being removed and some broken away.

Fig. 4. is a fragmental horizontal sectional viewon the line of Fig. 1.

Fig. 5 is a vertical sectional view on the line 55 of Fig. 4.

Similar reference characters designate similar parts in the different views.

1 designates an ordinary windmill tower on which is horizontally revoluble a suitably constructed frame 2 which is mounted upon a base which is supported by balls a mounted in a ball race provided in the upper side of a top plate which is secured to the top of the tower l.

Rotatably mounted on the frame 2 are two wind wheels, each having a horizontal shaft 6 rotatable on the frame 2 and provided with front and rear cranks 7 and 8, set quartering to each other.

Secured to each shaft 6 are radial arms 9, to which are respectively pivoted blades 10, eachof which has at one sideof its pivotal point'an area adapted to be exposed to the wind greater than the area at the opposite side of the pivotal point. An excess wind pressure will thus cause the blade 10 to be swung from the into-the-wind position, shown in solid lines in Fig. 2, to the position, for instance, shown in dotted lines in said figure.

For automatically swinging the blades 10 of each wind wheel toward the into-the-wind position, the following described mechanism is provided.

Pivoted on a horizontal bar 11, mounted in the frame 2, is a substantially horizontal lever 12, which at one side of the bolt 11 has mounted on it a longitudinally slidable weight 13, which is adapted to be secured in position by a set screw 14:.

fit the other side of the pivot bolt 11, the lever 12 has pivoted to it the upper end of a link 15, the lower end of which is pivoted to a crank arm 16 which is provided at the center of a longitudinal rock shaft 17, which is pivotally mounted in brackets 18 secured to the frame 2. I

Two sleeves 19 are respectively slidably mounted on the wind wheel shafts 6. Each sleeve has pivoted to it one set of ends of a plurality of radial rods 20, the opposite set of ends of which are pivoted at the points 21 to the blades 10 respectively. As will be seen in Fig. 2, the pivot points 21 are each located at the inner'side of a straight line connecting the pivot points of the adjacent blade 10 with the arm 9 and the pivotal point of the inner end of the adjacent rod 20. This construction permits the forward sliding movement of the sleeve 19 to readily swing the blades 10 out of the into-the-wind position.

The rock shaft 17 is provided also with two crank arms 22, the'upper ends of which are respectively pivoted by bolts 23 with the rear ends of two arch-shaped links 24, F1g. 3, the forward ends of which are respectlvely pivotally and rotatably connected in any suitable manner with the sleeves 19 Preferably the pivotal points of the rear ends '1 1 of the links24 are disposed respectively substantially in longitudinal alinement with the aXes of the wind wheel shafts 6. By means of thisconstruction, the crank arms 22 being disposed nearly vertical and having but a Fig. 1.

limited swinging movement at opposite sides of the vertical plane of the rockshaft 17 the thrust of the links-24 is substantially along the axes of the shafts 6, thus eliminating a great deal oflfriction when the links c 24fare employed to pull the sleeves 19 rearwardly in throwing the blades toward the intO-the-Wind. position. b

The weight 13 in swinging downwardly the forward end of the lever 12, through the intermediacy of the link 15 and crank arm 16, rocksthe rock shaft 17 clockwise,

as; viewed in Fig. 3', thereby sliding the sleeves 19 rearwardly on the shafts 6, through the intermediacy of the links 24,

thus swinging the blades 10, by meansof the rods 20 to theinto-the-wind position, shown in solidlines in Fig. 2.

For'swinging the blades 10 out of the wind or to aposition shown in dottedlines in Fig. 2, the lever-12 adjacent to its rear 1 end has secured to it the upper end of a 'rope 25, which passes over a roller 26 on the base plate 3, Fig.3, and has its lower end secured to a horizontally extending arm 2? of a sleeve-28 whichis vertically slidably 'mounted'on a vertical member 29,the lower end of which is swiveled to the upper end pump rod 30, as "shown in of c a vertical The, sleeve 28 is provided with an annula'r peripheral groove 1 31 in which is mounted the bifurcated end of a horizontal member 32, which is secured rigidly to a vertical rod 33, whichis slidably mounted in bearings 34 secured to the tower 1, and which has its lower end fastened to the upper endof-a depending rope 35.

An operator standing on the ground by pulling downwardly on the rope 35 will swing the rear end of the lever 12 downwardly, thus rocking the rock shaft 17 counter-clockwise, as viewed in Fig. 3, thereby throwing the blades 10to the outof-the-windposition, by means of the mechanism already described.

For vertically reciprocating the member 29 and the pump rod 30, the following mechanism is provided. A horizontalshaft .36 rotatably mounted on the frame 2 near the middle thereof and parallel with the wind wheel shafts 6 is provided at its f0rward and rearends respectively with crank arms 37 and 38, Figs. 1 2 and 4. Pivoted to the cranks 7 and 37 is a longitudinal horizontal transmission bar-39. A similar transmission bar 40 is pivoted to the crank arms 8 and 38. These bars may be ordi-' nary wooden bars easily obtainable by, any

farmer.

Splined to the shaft36 Jand' longitudi- "nally'slidab-lethereon are two clutch members 41 and 42 which are adapted to respectively engage teeth in the opposite ends of a pinion 43, Figs. 4 and 5, whichis rotatably mounted on the shaft 36.

A coil spring 44 encircles the shaft 36 and has one end bearing against a collar '45 secured to said shaft, and has its other end bearing against the clutch member 41 so as to normally hold said clutch member engaged with the pinion 43. The arrangement of the teeth in the clutch member 41 and the adjacent end of the pinion 43is such that the clutchmember will drive the pinion at the same speed as the shaft 36,

and in the same direction, andwill permit 1116131111011 at t mes, as hereinafter described,

to be rotated faster than the shaft 36.

The pinion 43 engages with an internal pinion will'engage the row of teeth 47 and I will thereby lift the member 29, the pump" rod 30 and the gear 46, thus lifting the load of water which is carried by the pump rod 30 and member 29. 'The'row'of teeth 47 r are preferably disposed, when in mesh with the pinion 43, in vertical longitudinal alinement with the member 29 and the pump rod 3'O,as shown in Figs. 1 and 5.

By means of this arrangement, on the up stroke or working stroke of the pump rod,the load is in direct alinement' with the row of teeth 47, thus efl'ecting a straight pull, and eliminating torsional strain and liability of breakage ofthe gear or bar 29. c

Whenthe pinion 43 has reached the lower end of the vertical row of teeth '47, it will engage the teeth 50 at the lower end of the gear, thereby shifting the gear 46 and member 29 to the left, as viewed in Fig. 5,

and causing the pinion 43 to engage with, I

the vertical row of teeth 48. member42 has teeth so arranged that it will, when engaged with the pinion 43, hold said pinion from rotating faster than the The clutch shaft 36, when the pinion is engaged with the vertical row of teeth 48 and the weight of the parts supported by the gear 46 is sustained by the pinion.

Upon :the completion of the downstroke of the ,pump rod :and gear 46,, 1 the :teeth 49 beingengaged withithe ipinion e3,-.the :rotation of the latter will shift, thegear 4e and member 29 to the .right, as viewed in Fig. :5, .thus causing. the pinion to irengage the teeth 47 and therebyagain lift the pump, rod 30 as before described.

For .retainingthe pinion .43 constantly engaged with {the gear 46, any suitable mechanism :may be provided. In the drawing, I Ehave shown .vfor :this purpose, :a vertical plate 51 secured to one edge of the gear 46, Fig; ;5,and adapted .to :have one side bear against {two rollers :52, which .are respectively {mounted upon two upwardly extending projections 531011313116 upperside of thebase3, when the gear .46 .movesrdown- Wardly. Whensaidgearhas completed its downward stroke, [the pinion 4-3 :will shift, the gear laterally, so :that the opposite side of theplate '51 wilL-engage the rollers 52..

111 Order thatithe tgfiflfftfi shall atom with the framexZ, as. said frame is swung bythe. wind, the gear. 46. {has secured to. its upper end a flat-vertical :bar 54 which is slidably mounted and .laterallyoscillatable in a slot 55 provided Iinzthe uppenend o-fathe frame, 2, as shownin iFiig; 2.,

In i order that {the clutch :member 142 may be released, from or retained engaged with the pinion -43, said 'clutch imember "has pivotally and rotatably vconnected with it a lever 56, Fig. 4:, ,which is pivoted -.to the base -platez3. A coilispringso'f attached to the frame 12 and to. :ithe lever 56 :normally holds said lever in a LPOSllBlOIl which the clutch member 421Will engage thepinion 43.

For withdrawing the clutch member 42 from engagement with the pinion 43, the lever 5.6 ,;has secured to it. a 10136.58 which passes over :alpulley :59 mounted ion the base 3. By pulling downwardly on the rope 58, the clutch member 42 willxbedisengaged from "the pinion 43. When this is.

done and :theipiniontengages the gear teeth 48 on athe down SbI'Qk$,fithetWGightKlfll'FlGd by the gear 46' will ficause zthe gear, :member 29 and the pump rod 30zto drop rapidly .by gravity, thereby :rotating, the pinion 43 faster than the shaft:86. This increases the rapidity of the sreciprocation of ,therpump rod, :thus throwing an additional load upon the wind wheels.

In case of excess wind .pressure, v:the weight 13 may be adjusted forwardly :on the lever .12, so as to force :the blades :10 more into the intoethewindposition, and atsthge same time,a weightaGO, Fig. 1,,maybe hung onto .the :lower :end of the :rope a58,.so

pump rod 30willvnow fallby "gravity atthe end of the .upstroketand *thewpinion 43 will rotate faster than the;.pshaft 36: and also faster than the wvind wheels, so that the, pump rod :will be reciproeated more rapidly .thus increasing the load thrown upon the wind wheels and thereby preventingthem from revolving too rapidly. The powercof strong .windstmay be :thus utilized to increase the capacity of the wind :mill without liability of its being damaged.

When/the wind moderates, .the weight 6.0 may :loeremoved from the rope 58, and the weight 13 readjusted rearwardly .on the lever 12 to correspond with the velocityof the .wind. The clutch member-42 will .now belocked withthe pinion 43, thereby holding the :zpinion from running faster than the shaft 36.,andthereby holding the pump rod from falling by gravity.

Secured rigidlytoithe frame 2 is a rearwardly extending vane. -61 which always keeps athe wind wheels in the into-the-Wind position.
